2020年2月7日 · In Figure 1, the P&WA testbed aircraft is shown landing at the Windsor Locks, Bradley International Airport, after a test flight, with a JT9D engine replacing two TF-33 inboard engines on the right wing of the eight-engined B-52. The B-52 continued as a P&WA testbed aircraft until 1981, even after being damaged in its hangar by a violent ...

2018年3月12日 · All early generation jet engine smoke like this at take off. This includes B707 and DC-8 and many other jet aircraft of the 1960's. Most airliners today have more efficient engine that do not smoke. The B-52 still uses older generation engines. All these older generation engines were designed when fuel was cheap.

2019年2月9日 · Back when reengening was considered it was thought the B-1 was going to replace the B-52 within the decade. Later it was thought the B-2 was going to replace the B-52 within the decade. Neither happened of course, the B-1 is gone and the B-2 looks to be the next to be replaced while the B-52 keeps soldiering on. $\endgroup$ –

2018年1月26日 · The B-52 was built in different versions (A-H) and the engines and their installation differ between these version 1. The image in the question most likely shows the engine configuration of a B-52H. The following drawings suggest that this also changed the inlet design 2. There seem to be different engine-designations depending on the application.

2018年2月8日 · A 2014 Aviation Week report, B-52 Re-engine Resurfaces As USAF Reviews Studies, said. Pratt & Whitney studied the idea in 1982, with four PW2000-series engines. In 1996 Boeing and Rolls-Royce jointly proposed to fit B-52s with four RB211-535s, with the government leasing the engines.

According to the video description, that B-52 belongs to the 2d Bomb Wing, which operates the B-52H variant. According to the declassified B-52H manual, the pilot flying should advance all the levers "deliberately and evenly" to the thrust gate. The thrust gate is adjusted prior to takeoff, usually by the copilot, to limit the levers to the set ...

2022年12月31日 · When used 60 years ago on the B-52 and 707, water injection increased thrust by about 30%. Enough water was carried on the 707 for about 5 minutes of takeoff and climb. Its system and the water added weight that could no longer …

The B-52 rudder and elevator have an exceptionally narrow chord. Most airplanes have at least a 25% chord, which allows sufficient power and effectiveness in both yaw and pitch during takeoff, landing, and asymmetric conditions. The same is not true of the B …

2019年11月11日 · All versions of the B-52 use the Pratt & Whitney JT3C turbojet (except for the last version, the B-52H, which uses the JT3D low-bypass turbofan instead). Problem: the JT3C is a horribly anemic engine, especially the early versions used on the A-E (producing a mere 44.5 kN per engine on the B-52A, increasing only to 46.7 kN/engine on the B-E ...

2016年12月13日 · This is a photograph from the launch of an X-43 from the NASA owned and operated B-52 '008'. It appears that one engine is producing a plume of smoke in the photograph.
